Simple chiller series, Water-cooled type
Cooling pump CHW-900
Code No.： 0073892-000
Simple chiller series can respond to various needs from the consumers by selecting various options. Proud of various kinds of pump abilities in available, which can meet a high flow rate and a high pump head. Pure water, etc. are available as an option.
Applications●Cooling of processing stage.
●The water-cooled integrated type is ideal for cleanroom.
Diverse optional accessoriesAll options except the standard specifications are available. Diverse pump unit specifications depending on Flow rate, Pump head and Materials (see the right page) are available to respond user’s various needs. Also, Upgrade for Pure water, Precise temp control etc. are available. Simple series enables to reduce wasteful spending by adding the minimum necessary upgrade.
Space savingAchieved to save the installation space by 65% compared with a conventional one. Contributes to the installation space saving and flexibility in the factory layout while remaining the cooling capacity.
Safety operation thanks to the warning indicatorThe warning indicator equipped with all models will be activated individually in case of emergency that enables deal with it promptly.
The detail of Diverse optionsThe lineup of “Simple series Chiller unit” are Four types of air-cooled and Three types of water-cooled. The series consists of basic functions with the minimal functions and capabilities to extend those as per customer’s request as an option.
The functions and the usage can be customized as one likes to prevent waste spending by adding the minimum necessary upgrade. This is the concept for “Simple series”.
The pumping capacity variations for the standard 7 models are as shown on the right depending on the options.

|(*1)There may be a case where temperature performance cannot be maintained due to environmental temperature, heat load, circulation pipe distance etc.|
|(*2)Capacity when the cooling water temperature below +25℃.|
|(*3)Capacity when using tap water. Flow rate when the discharge pressure of CHW-900 is at 0.12MPa and of CHW-1500/2200 at 0.3MPa.|
|(*4)Capacity varies with the water temperature. Please note it may cause defect if the flow rate does not increase at high temperature, so please confirm if the required flow rate being secured in advance.|
|●Power cable is not included.|
|●Pure water is available as an option.|
|●Please ask us when mixing chemicals for water treatment to circulating fluid.|
|●The fee for Delivery, Installing are quoted separately.|
|★Can upgrade the abilities and add some functions by selecting option.|
|1) To improve accuracy of temperature adjustment (changes to Hot gas bypass control or Pulse width modulation expansion valve) .|
|2) To improve capacity of pump unit (changes to Large flow rate / High head; Several types).|
|3) To add safety devices (No-fuse breaker and Earth leakage breaker).|
|4) To change materials such as of the valve for pure water, of the cooling coil, of the circulating fluid piping for the antifreeze and of the ball tap.|
|5) Addition functions (Special order/Option : Remote control box, To reduce noise by fan speed controller).|
|6) Other (Device fixing brackets).|
